4. QUESTION A bakery in Cape Town would like to produce a koeksister that could be marketed to consumers that are health conscious. They experimented with 4 different fats to see which fat was least absorbed by the koeksisters during the deep-frying process. Each fat was used for six batches of one dozen koeksisters each, and the table shows the grams of fat absorbed by each batch of koeksisters g Fat Absorbed in Batch Fat 1 64 72 68 77 56 95 72 13.34 Fat 2 78 91 97 82 85 77 85. 7.77 Fat 3 75 93 78 71 63 76 76 9.88 Fat 4 55 66 49 64 70 68 62 8.22 SS df MS F p-value Treatment 1636.5 545.4 5.41 0.0069 Error 2018.0 20 100.9 Total 3654,5 23 3.

Expert Solution
Step 1

In order to determine whether there is significant difference in between the mean scores of students of three different sections, a one way analysis of variance (one way-ANOVA) test needs to be conducted.

 If test result gives p-value<α, where α denotes the level of significance, then it can be concluded that there is significant difference in between the mean scores of students of three different sections.
